Custom policies can be created to supplement the system-defined policies of MRS. For the actions that can be added to custom policies, see Permissions Policies and Supported Actions > Introduction in MapReduce Service API Reference.
You can create custom policies in either of the following ways:
- Visual editor: Select cloud services, actions, resources, and request conditions. This does not require knowledge of policy syntax.
- JSON: Edit JSON policies from scratch or based on an existing policy.
Example Custom Policies
- Example 1: Allowing users to create MRS clusters only
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "mrs:cluster:create", "ecs:*:*", "bms:*:*", "evs:*:*", "vpc:*:*", "smn:*:*" ] } ] } - Example 2: Allowing users to resize an MRS cluster
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "mrs:cluster:resize" ] } ] } - Example 3: Allowing users to create a cluster, create and execute a job, and delete a single job, but denying cluster deletion
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "mrs:cluster:create", "mrs:job:submit", "mrs:job:delete" ] }, { "Effect": "Deny", "Action": [ "mrs:cluster:delete" ] } ] } - Example 4: Allowing users to create an ECS cluster with the minimum permission
- If you need a key pair when creating a cluster, add the following permissions: ecs:serverKeypairs:get and ecs:serverKeypairs:list.
- Add the kms:cmk:list permission when encrypting data disks during cluster creation.
- Add the mrs:alarm:subscribe permission to enable the alarm function during cluster creation.
- Add the rds:instance:list permission to use external data sources during cluster creation.
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "mrs:cluster:create" ] }, { "Effect": "Allow", "Action": [ "ecs:cloudServers:updateMetadata", "ecs:cloudServerFlavors:get", "ecs:cloudServerQuotas:get", "ecs:servers:list", "ecs:servers:get", "ecs:cloudServers:delete", "ecs:cloudServers:list", "ecs:serverInterfaces:get", "ecs:serverGroups:manage", "ecs:servers:setMetadata", "ecs:cloudServers:get", "ecs:cloudServers:create" ] }, { "Effect": "Allow", "Action": [ "vpc:securityGroups:create", "vpc:securityGroupRules:delete", "vpc:vpcs:create", "vpc:ports:create", "vpc:securityGroups:get", "vpc:subnets:create", "vpc:privateIps:delete", "vpc:quotas:list", "vpc:networks:get", "vpc:publicIps:list", "vpc:securityGroups:delete", "vpc:securityGroupRules:create", "vpc:privateIps:create", "vpc:ports:get", "vpc:ports:delete", "vpc:publicIps:update", "vpc:subnets:get", "vpc:publicIps:get", "vpc:ports:update", "vpc:vpcs:list" ] }, { "Effect": "Allow", "Action": [ "evs:quotas:get", "evs:types:get" ] }, { "Effect": "Allow", "Action": [ "bms:serverFlavors:get" ] } ] } - Example 5: Allowing users to create a BMS cluster with the minimum permission
- If you need a key pair when creating a cluster, add the following permissions: ecs:serverKeypairs:get and ecs:serverKeypairs:list.
- Add the kms:cmk:list permission when encrypting data disks during cluster creation.
- Add the mrs:alarm:subscribe permission to enable the alarm function during cluster creation.
- Add the rds:instance:list permission to use external data sources during cluster creation.

- If you need a key pair when creating a cluster, add the following permissions: ecs:serverKeypairs:get and ecs:serverKeypairs:list.
- Add the kms:cmk:list permission when encrypting data disks during cluster creation.
- Add the mrs:alarm:subscribe permission to enable the alarm function during cluster creation.
- Add the rds:instance:list permission to use external data sources during cluster creation.
